COFFEE-POT.

Speccaton of Letters Patent No. 23,021, dated February 22, 1859.

To all whom 'it may concern:

Be it known that I, JAMES I-I. FREETo, of Vheaton, in the` county of Du Page and State of Illinois, have invented a new and Improved CoHee-Pot; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, represents an elevation of my coffee pot. Fig. 2, a vertical central section of the same.

Similar letters of reference indicate corresponding parts in the two figures.

The object of this invention is to preserve the flavor of the coffee, a great portion of which escapes otherwise with the steam which ris-es when hot water is poured over the ground coffee, and the invention consists in arranging two valves in connection with suitable pipes in a condensing vessel which is placed in a cistern containing cold water in such a manner that the steam which rises from the hot coffee is condensed and carried back to the pot under all circumstances, so that the flavor of the colfee is perfectly preserved.

To enable others skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A, is a coffee pot, the outward shape of which resembles a common pot for the same purpose, and B, is a hoop which lits into the upper part of the pot A, and which rests on a ring a, which is attached to the sides of the pot. This hoop is provided with a cross bar o, which4 serves as a handle to take the same out and put it in, and it (the hoop) serves to hold the strainer C, in its place. This strainer is made of linen, cloth or other suitable material and it is bent over the under edge of the hoop B, and forced down on the ring a, as represented in Fig. 2.

D, is the spout which communicates with the pot by an opening c, which is closed by a flap valve E, which is operated by means of a rod el, which extends to the outside of the pot under t-he handle F, where a knob e, is attached to its outer end so that it can be operated with the same hand which holds the pot. The rod d, passes through a stuifing box f, which is fitted into the side of the box in order to -make a tight joint at the place where the rod passes. A small pipe 0, admits air into the pot in order to get the necessary pressure to make the liquid flow from the spout if the valve E, be

tom of this cistern is attached the condensing chamber H, which is open at the bottom and which connects with a tube I, by means of an opening lz., in its top. The opening h, is closed by a valve z', which is pressed down by a spiral spring y', which is attached to the stopper J, by which the tube I, is closed. The stem c, of the valve z', extends up and down and a valve Z, is attached to its lower end which closes the opening of a pipe K, which communicates with the cistern. A rod m, serves to steady the pipe K, in its position. The tube I, communicates with the spout D, by means of a small pipe L, which extends through the bottom of the cistern G, to a socket a, from which another pipe M, leads to the spout.

The operation is as follows: The ground coffee is placed in the strainer and hot water is poured over it, and the pot is closed by placing the cistern over it. The latter vessel is filled with cold water and the steam rising from the hot coffee in the pot enters the condensing chamber II, where it is condensed by coming in contact with the cold sides of the same. Should the steam, however, form quicker than it is condensed-by.

the chamber II, the valve z', is forced up by the pressure of the `steam and the valve Z, is

lifted from the4 opening of the pipe K, so that a jet of cold water from the cistern is introduced into the chamber H, which condenses the steam contained therein at once, and the steam which has escaped by the .valve z', is carried through the pipe L, down to the spout, and in passing through this pipe, which passes through the cold water in the cistern, the steam is condensed, so that it is deposited in a liquid form in the inner end of the spout where it mixes with the coffee as soon as the flap valve E is opened. By these means the flavor of thecoffee, which would otherwise escape with the steam rising from the same, is fully preserved.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is :M

l. The arrangement of valves z', and Z, in

the condensing chamber H, in connection l with the coffee pot A, by means of a flap with the pipes L, and K, whereby the steam Valve E, which is operated by a rod d, When 'which escapes through the valve i, is carried the same is applied to L coffee pot which is ol1 and deposited in e liquid state into the hermetically closed by a gasket g, in con- 5 spout, While at the same time, by the action nection With the air-tube o, substantially as 15 of the steam, a jet of cold Water is admitted and for the purpose specified.

into the chamber H, substantially as and for JAS. H. FREETOL the purposes specified. Vitnesses:
